Version 0.53 adds several new features which include:
VRAM buffer management is now fully implemented. The driver can now handle 3D drivers allocating more buffers than fits in VRAM.
Intelligent shadow buffering of VRAM buffers added - reducing the need to copy the buffer back out of VRAM should it be paged out again without being modified.
The RadeonHD_RM.resource is now enabled.
To put the driver through its paces its developer, Hans de Ruiter, has created a short test program for Radeon HD 4000 series cards which renders a fly-through of a 3D scene whose textures and geometry take up more space than is available in VRAM. This program along with another test demo are included on the download page.
According to Hans, version 0.53 is now fully ready for 3D support to be added by Hyperion Entertainment. Work to support the Radeon HD 7000 series "Southern Island chipsets"is ongoing, but a number of important enhancements, including Blitter acceleration, have already been implemented.
About the Radeon HD driver: The driver supports 2D and Compositing under AmigaOS 4 with a wide range of Radeon HD PCI graphics cards including: the X1300-X1950 series, HD4000 series, "Evergreen" HD5000 series and "Northern Islands" HD6000 series. Work to support the "Southern Island" HD7000 series is ongoing. Please visit AmigaKit's website to obtain compatible graphics cards.
About the developer: Hans de Ruiter is an electrical & electronic engineer and leading AmigaOS developer and Amiga enthusiast. His website - HDRLab - details various projects, many of which are AmigaOS related. The biggest of these is the RadeonHD driver for AmigaOS, an ambitious project that aims to deliver modern graphics capabilities for the AmigaOS platform.
